Wherein the front-back direction is parallel to the moving direction of the resistor. Specifically, when the incoming material resistor 5 needs to be moved forward, the first driving member 11 drives the first positioning member 12 to move upward, so that the incoming material resistor 5 is separated from the second positioning member 14 and is clamped to the first positioning member 12, then the second driving member 13 works to push the first driving member 11, the first positioning member 12 and the incoming material resistor 5 on the first positioning member 12, so that the incoming material resistor 5 moves forward at least one distance (the distance between adjacent resistors is the distance), that is, at least one resistor moves to the material cutting mechanism 2, then the first driving member 11 drives the first positioning member 12 to move downward and return to the initial position, so that the incoming material resistor 5 is separated from the first positioning member 12 and is simultaneously clamped in the second positioning member 14, and during the downward movement of the first positioning member 12, the second positioning member 14 carries and positions the descending incoming material resistor 5 again, so that the incoming material resistor 5 can accurately fall into the second positioning member 14, ensuring that the displacement of the incoming material resistor 5 is integral multiple of the spacing distance. Finally, the cutting mechanism 2 cuts the extended resistor, separates the resistor from the feeding resistor 5, and receives the cut resistor by the feeding mechanism 3.

The second positioning member 14 is also provided with a plurality of clamping portions 121 for receiving the incoming material resistors 5, and the plurality of clamping portions 121 are sequentially arranged along the moving direction of the incoming material resistors 5.

Furthermore, the first positioning member 12 and the second positioning member 14 can be closely arranged, so that the influence on the size of the transportation mechanism 1 is small.

The bearing plate 41 is used for bearing the supplied material resistor 5, so that the supplied material resistor 5 can be flatly laid on the bearing plate 41, and the movement of the auxiliary transportation mechanism 1 prevents the rear end of the supplied material resistor 5 from having an excessive pulling force when the first positioning piece 12 moves the supplied material resistor 5.

In one embodiment of the present invention, referring to fig. 1 to 3, the resistance feeding mechanism further includes a frame 4, and the frame 4 is used for supporting the whole mechanism.

Specifically, when the first sensor 23 detects that there is a resistor below the cutting blade 22, it indicates that the conveying mechanism 1 has advanced the incoming resistor 5 and is ready for cutting. Then, the first sensor 23 transmits a signal to the control system, and the control system controls the third driving member 21 to move downward, so that the cutting knife 22 can cut off the pin of the resistor, and after the pin is cut off, the third driving member 21 drives the cutting knife 22 to return to the original position to prepare for the next cutting.

The cross section of the positioning groove 311 may be V-shaped, so that the resistor does not need to fall precisely, and a certain offset distance may exist between the position of the resistor when falling and the center of the positioning groove 311. The fourth driving member 32 is used for driving the receiving block 31 to move back and forth between a material cutting position and a material transferring position, wherein the material cutting position is below the cutting knife 22, and the material transferring position is a position where the resistance is to be transferred. The connecting pipe 34 is arranged opposite to the material moving position (the axial direction of the connecting pipe 34 is the same as the axial direction of the resistor), and when the material receiving block 31 moves the resistor to the material moving position, the fifth driving piece 33 pushes the resistor on the material moving block to the connecting pipe 34.

Of course, in other embodiments, the moving direction of the fourth driving member 32 may be perpendicular to the transporting direction of the resistor or at an acute angle, as long as the resistor can be quickly withdrawn from the cutting blade 22.

Alternatively, the moving direction of the moving end of the fifth driving member 33 is perpendicular to the transporting direction of the resistor, i.e. the moving direction of the resistor is perpendicular to the transporting direction of the resistor on the transporting mechanism 1 when the resistor on the receiving block 31 is pushed. Thus, the movement stroke of the fifth driving member 33 can fully utilize the width space of the resistance feeding mechanism, so as to avoid the overlong length of the resistance feeding mechanism. In other embodiments, the moving direction of the moving end of the fifth driving element 33 may be parallel to the transporting direction of the resistor or disposed at an acute angle, as long as the moving direction of the moving end of the fifth driving element 33 is parallel to the axial direction of the connecting pipe 34.
